And your Lord would not have destroyed the cities unjustly while their people were reformers.
The Saheeh International Quran Translation
وَمَا كَانَ رَبُّكَ لِيُهْلِكَ ٱلْقُرَىٰ بِظُلْمٍ وَأَهْلُهَا مُصْلِحُونَAnd your Lord would not have destroyed the cities unjustly while their people were reformers.
